Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic system or equipment for removing liquid from yarn skeins or yarn skeins carried by a holding village, and to a skein transfer method using this equipment.

In modern textile factories, yarn skeins that have undergone some degree of wet processing, e.g. dyeing, are arranged in a cabinet (dyeing cabinet) or a transport trolley, supported and spread between two holding villages inserted into the skeins. It is being

For further processing of this skein, each retaining village is removed by hand from the dyeing cabinet or trolley, in which case one of them is extracted and the remaining retaining punches are removed from the feed chute of the drawing device along with the suspended skein. The current standard practice is to place it in A pair of pliers of the wringer then grab each retaining punch (along with the hanging skein) and move it;
Place both ends on the support cups on the slides of a pair of wringer, and place the retaining village between or in the gap between a pair of wringer rollers consisting of one drive roller and one idle roller. Lowering: The wringer rollers are then moved closer together, the pinched skein is pulled up (thereby squeezing it), and a pair of pliers transports it along with the holding village over the unloading chute. From there, the skein is typically grasped, removed from the holding village, and placed onto the skein holder or skein carrier support of the supply chain within the dryer, also by hand. The known equipment summarized above requires management by at least two operators and is therefore relatively expensive.

Moreover, the work is demanding, and the repeated manual handling of the skeins often causes the threads to become tangled, which requires time to unwind. Another disadvantage is that the lengths of the holding punches in skein processing equipment currently vary, and in the past, conveyors and wringer have been manufactured with different lengths depending on the size of the holding punches used in each piece of equipment. It had to be made to size. It is therefore an object of the present invention to mechanize the drawing and transport operations for the skeins as far as possible, and to provide a universal design which is compatible with any existing system for removing water from threads moving with a holding village of a predetermined length. The purpose of this invention is to provide a throttling system or equipment.

This is achieved by the equipment and method according to the invention.

The method according to the invention essentially consists of using two large holding panels to extend the skeins coming out of the dyeing cabinet;
The holding villages are moved close together and the skeins suspended in a pair of closely spaced holding punches are conveyed through the feeding device of the wringer to the wringer or wringer; the skeins coming out of the wringer are then held for spreading. The method comprises the steps of: separating the villages from each other and stretching the skein so that the skein support of the transfer device can be inserted into the skein; then simultaneously removing both retaining villages from the skein; The equipment for carrying out the above method essentially consists of a chain feeding device to the wringer, a roller wringer, an unloading conveyor or wringer and a skein transfer device and a retaining village removal unit.

The wringer feeding device consists of a chain conveyor in which two chains spaced apart are moved parallel to each other in stages and intermittently, and both chains have a depth and width capable of receiving two overlapping holding villages. It is made of plates with round notches, and there is sufficient space between the chains to accommodate the skein suspended from the holding punch.

Typically, the squeezing device has at least one pair, preferably two pairs of retaining village pliers (one pair of inlet pliers and one pair of outlet pliers).

The inlet pliers are on a pair of wringer vertically movable slides for picking up the retaining punches in pairs by a feeding device and lowering the skein between squeeze rollers, one of which is a normally driven roller and the other an idle roller. Place both ends of the holding village in the cup. The outlet puller collects the holding village from the cup and places it on the unloading conveyor. According to the features of the present invention,
The jaws and cup of the pliers are shaped and dimensioned to receive the two holding villages in a parallel and overlapping manner. Further features of the invention provide that when the skein is pulled out of the space between the squeeze rollers, a "blow" (
In order to avoid blows), a freewheel device is applied to the driven rollers. The wringer unloading conveyor is characterized by a chain conveyor with two parallel, intermittent chains with sufficient spacing between them for the skeins to hang.

In particular, each chain consists of a plate with a notch large enough to receive only one retaining punch, and a plate with no notch.
Holds more than one plate alternately. This chain conveyor cooperates with a guiding and clearing device downstream of the wringer outlet pliers to separate the two pairs of retaining punches of each skein group from each other, and by means of the pair of retaining holes at this distance, the skeins are to an expanded state. The installation according to the invention comprises two pairs of widely spaced holding punches carrying the skeins, suspended from the unloading chain and taken up by another device, such as an expandable rod device for yarn transfer. It also features a pliers transfer device suitable for picking up the two holding punches by the pliers; this transfer device is not necessarily essential to the present invention, and can be replaced manually in some cases, but this If the transfer device is installed on the exit side of the unloading device, the object of the present invention can be further achieved.

Furthermore, according to an important feature of the invention, the entire device is arranged so as to be easily adapted to any holding punch size. In this installation, adaptation to the length of the holding village is such that elements designed to hang the ends of the holding village (i.e. chains for chain conveyors; hook supports for wringer and transfer devices) are placed in the direction of movement of the thread skein. This is made possible by providing well-known adjustment devices, such as screws and internal threads, mounted on a frame carried on a slide bar at right angles to the cylindrical frame and controlled by a handwheel or other known means. The benefits achieved by the present invention essentially consist in a reduction in the number of workers and the associated reduction in operating costs; a reduction in yarn entanglement and the associated reduction in unwinding costs; and a high degree of equipment flexibility. .

The equipment and method of the present invention will be explained below based on the embodiments shown in the accompanying drawings. With reference to figures 1 and 2 of the accompanying drawings, a thread skein (indicated by 1) on a holding punch (indicated by 2)
A novel method and equipment for automatic operation, squeezing operation and subsequent automatic feeding of the skein to any known transfer device will be briefly described.

In the figures of the accompanying drawings, reference numeral 11 indicates a supply conveyor or feeder, 12 indicates a squeezing unit, 13 indicates an unloading conveyor for the squeezer, and 14 indicates a skein transfer device. The arrow indicates the direction of movement of the skein. The device shown at 15 in FIG.
Any rod skein transfer device that can move linearly or rotate and spread; suitable devices are disclosed in various co-pending applications by the same applicant. The equipment outlined above is intended to be installed downstream of yarn dyeing equipment and other equipment where it is necessary to remove liquid from yarn skeins.

In the dyeing cabinets currently in use, the skeins are carried stretched between two holding panels 2 inserted therein. When removing a skein (by hand) from a cabinet, hitherto the usual method was to immediately remove one of the two holding punches 2, but in the novel method of the present invention, one of the two holding punches 2 is immediately removed. The operation of removing one of the holding punches is eliminated, and the two holding punches 2 are moved closer together to support the skein 1 during the drawing process. A retaining village is used to widen the skeins sufficiently to allow the insertion of support rods for skein withdrawal. Each part of this system will now be described in further detail.

In the novel system according to the invention, the feeding device to the throttle unit 12 is a chain device, as shown in FIGS. 3, 4, 5, 6 and 7. This device has two chains 21
and 22 (shown in dashed lines for simplicity in FIGS. 4 and 5), gear wheels 24 and 25 for chain 21 and gear wheel 26 for chain 22, respectively.
and 27 in parallel. gear wheel 2
4 and 26 serve as driving functions for the respective chains. In practice, only one of said two gear wheels 24 or 26 is intermittently driven by a drive unit of various types (not shown), preferably through a freewheeling device (not shown as it is known to those skilled in the art). driven by The two gear wheels 24 and 26 are connected by a gear wheel 3 that connects gear wheels 29 and 34 at its ends.
1 and 33, the gear wheel 34 is attached to the axis 35 of the gear wheel 26 and the gear wheel 29 is attached to the axis 28 of the gear wheel 24.

The intermediate shaft 32 needs to be located above the chain path and away from it so as not to interfere with the skein being transported.

Along with the respective shafts 28, 36, 35, 37, the chain gear wheels 24, 25, 26, 27 are mounted on bearings 38 integral with the movable bars 40 and 41.

The movable bars 40 and 41 have bushing supports 42, 43,
44, 45, it is held by a pair of guides 47 and 48 arranged perpendicularly to the chain, and can slide. The guides 47 and 48 are held at their ends by upright frames 49 and 50;
Further, the intermediate shaft 32 is rotatably attached to this frame. Said bars 40 and 41 held by guides
The movement may be effected by various suitable devices such as screws and internal threads shown at 51 and 52, for example. The positions of the gear wheels 24, 25, 26, 27 when they approach each other are shown by chain lines in FIG. According to an important feature of the invention, the chains 21 and 22 described above are formed from a plate member 54 secured to a chain member 54' which is hinged by an insertion roller 55, as shown in FIGS. It has become.

Substantially, each plate member has a base 5 of a different shape.
6' and comprises a plate 56 provided with a notch or notch 57 of sufficient dimensions to receive two retaining villages in an overlapping position as shown in FIGS. 6 and 7.
These notches or cutouts 57 are narrower than the retaining village heads 2' so that the heads slide outwardly of each plate. A metal strap 58 is provided extending perpendicularly from plate 56 to receive the head. Next, the o-ra diaphragm unit shown in FIG. 3 (partially schematically shown in this figure) and FIGS. 8, 9, 10, 11, and 12 will be explained.

This throttling unit is typically, for example, a cylinder coating 61'.
This allows horizontal movement along the slide guide 61.

It consists of a puller holding frame 60. This frame has four vertical slide rods 62 by means of which a carriage 65 can be moved up and down by means of a cylinder device 64, and this carriage 65 has horizontal slide rods (shown in FIG. 9) perpendicular to the guide 61. It has 66,66. To adjust the distance or spacing, the two plier retaining heads 68, 68 can slide on the horizontal slide rods 66, 66 mentioned above, and the movement of bringing the heads 68, 68 closer together or farther apart is performed by a worm screw device or assembly 6.
Controlled by 9. In FIG. 9, the heads in the farthest state are shown by solid lines, and the heads in the closest state are shown by chain lines. In the remaining head positions, each head has two pliers and an associated control cylinder arrangement. FIG. 10 shows the associated pliers designated by only one head 68, 70 and 71, and its control cylinder arrangement. Each plier extends downwardly and can be moved within a corresponding slot 74 provided in the box-shaped carriage 65 to adjust the distance or spacing. Each Praya,
For example, pliers 701 in FIG. 8 consist of a body 76 having a pair of jaws 77, 78 supported at 77' and 78', respectively. The tips or ends of the jaws, designated 79 and 80 respectively, are carried into recesses or cavities in a slider 81 which slides within the body under the operation of the respective cylinder arrangement or unit 72. The jaws are opened and closed by the movement of the slider 81 relative to the body 76. In FIG. 8, the closed or close state of the jaws 77 and 78 is shown by solid lines, and the separated or open state is shown by iron lines. This jaw has a special shape, the extension forming a space or recess 83 for receiving the two overlapping retaining holes 2,2.
From the foregoing, it is clear that once the spacing or distance between the heads is adjusted, the pliers can be moved as one assembly in a horizontal sliding direction and up and down.

Of the four pliers, two pliers close to the feeder constitute the inlet side set, and two close to the unloading device constitute the outlet side set.

Normally, the diaphragm unit (Fig. 3) includes a diaphragm roller 85 at a fixed position that rotates in the direction shown by the arrow, and a cylinder device or unit 88 that moves between the positions shown by the solid line and the position shown by the broken line in Fig. 3. It consists of a movable idle aperture roller 86. According to a preferred embodiment of the invention, the operation of the rollers 85 is carried out by various types of freewheeling devices in order to avoid any shock between the rollers due to the difference in peripheral speed between said rollers when extracting or removing the skeins. It will be done. Said rollers 85 and 8
The lowering of the skein between 6 is effected by a pair of opposed slides 90 (only one of which is shown in FIG. 3) having supports or bearing cups for the ends of the retaining village 2. be exposed.

Each of said slides is controlled by a cylinder device 93 and can slide vertically along guides 91 and 92. The two slides 9 are interconnected by a connector 94 for simultaneous operation. According to a preferred embodiment of the invention, the support or cup (such as the cup 96 shown in FIGS. 11 and 12 on a larger scale with respect to FIG. The slide 901 is of sufficient size to accommodate holding holes of different lengths, but has interchangeable cups of different sizes (shown in solid and dashed lines in FIGS. 11 and 12). be prepared. The operation of the squeezing unit will be described next, but the chain unloading device that takes out the squeezed skeins from the squeezing machine will be described below. The unloading device is particularly
It is shown in Figure 6. The unloading device consists of two suitably moving parallel chain members.

The members are supported by bars (such as bars 40 and 41 for feeder 5) that move on orthogonal guides so that they can be moved closer and further away from each other to accommodate holding preferences of various lengths. . The assembly up to this point is similar to that of the chain feeder, and therefore is not shown in the drawings or described in detail. Instead, we will discuss different features. For example 1
Each chain of the unloading device, designated 00, consists of a plate section secured to a chain member which is hinged to each other through small rollers 1101. These plate members are generally eg 101 and 1
There are two types denoted by 02. Partura 101 is 1
It has an upright plate welded to the base 101' having a recess or cavity 103 which receives only the book retention village 2 (in Figure 15 the retention village is shown as a cutaway in the recess or cavity). There is. This section 101, also shown in the top half of FIG. 16, preferably, but not necessarily, has a metal strap 104 that protrudes and overlies the retaining section head. Also, the member 102 shown in the lower half of FIG. 16 has no depressions or voids and has a continuous surface 102a at the same level as the upper surface 101a of the member 101. This continuous surface is preferably folded green 1
Including 06. The chain 100 described above includes members 101 and 10.
Consists of 2.

Generally, the sections 101 and 102 are arranged alternately, that is, one section 101 is followed by one section 102, but depending on the width of the spread given to the skein, two or more sections may be arranged for one section 101. The backing materials 102 can be arranged, or the members 102 can be omitted depending on the case. The chain 100' advances intermittently (intermittently) at steps or pitches equal to four times the chain pitch or the distance or interval between each of the first and third spaces.

Any method may be used for forward movement, but the cylinder unit 11
1' and a gearwheel coupled to a chain drive gearwheel 113, preferably by the Liberty system. FIG. 16 shows the shaft 114 for the gear wheel 113. This shaft 114 is supported in bearings 115 and carries a gearwheel 112, a freewheel arrangement, and an intermediate gearwheel 116 for driving a further chain. A bearing surface 117 for the chain is also shown in FIG. The exit pliers of the wringer are configured to eject a pair of overlapping retaining villages 2 with their skeins suspended onto an unloading device.

In order to separate and space the two holding villages, and since an empty space is provided on the unloading chain of the unloading device for one holding village, each chain is equipped with a cam separator 120 (third , 13, 14) are fixed to the positioning layer of the movable bar, and two side plates 121 and 1 are attached to the outside of this cam separator.
22 and a bottom plate 123, these plates form an introduction configuration and can be adjusted in position during assembly of the system.

This fu. The rate or cam 121, 122, 123 is
The lower retaining punch, which fits into the recess or cavity 103 in the chain member, moves forward as the chain moves forward;
The upper retaining pestle 2 is pressed until the remaining retaining village meets the next new empty recess or cavity 103 into which it can fall.
Stop it. Preferably, the plate 122 described above is
To avoid the inconvenience of overlapping retention villages becoming bound, they are kept in place by graduated springs. With reference to FIGS. 17 to 20, a transfer or transfer device for transferring or transferring the skein or skein to another conveyor device and extracting the holding punches will be described.

This transition device is shown at i4 in FIG.

The device consists of a support frame, generally indicated at 130, which will not be further described as it depends on the arrangement of the system. The frame 130 is
It carries two horizontal slide guides extending a length above and substantially parallel to the chain unloading device, which guides are indicated at 131 and 132 in FIG. A frame, indicated generally at 133, is slidable over said guides 131 and 132, and 1
It consists of two orthogonal slide bars designated 34 and 135. The two plier holding heads 138 and 140 are attached to the slide bar 134 for spacing adjustment.
and 135.

Adjustment of the distance between said heads 138 and 140 by the length of the skein retaining village takes place with a screw 141 operated by a handwheel 142. One such plier retaining head, such as head 138, will now be described in more detail with reference to FIG. 19 of the accompanying drawings.

The bra retaining head 138 has two seats 134' and 1 at its end for sliding over bars 134 and 135.
It consists of a block 143 formed with a diameter 35', in the center of which is shown an internally threaded hole 141' for the 0 of the adjusting screw 141. This block 143 is an extension member 14 consisting of two tubes or hollow members.
6 and 147, and each hollow extension has a sliding rod therein connected to the piston of the cylinder device.
In FIG. 19 this member is illustrated with respect to only one of the pliers, where the rod is indicated at 148 and is connected to the stem 150 of the cylinder arrangement.
Next, the rod 148 is moved to the slider 5 at the pond end.
3, and in the cavity 154 on its side, the whole 1
Ends 155' and 156' of plier jaws 155 and 156, indicated at 58, engage. The jaws 155 and 156 each have a pin 1 in the body 59 of the pliers.
55'' and 156'', and is formed to have a recess or recess 160 when closed to receive the retaining village 2 whose outline is shown in dotted lines in FIG. Vertical movement of rod 148 within member 146 causes movement of slider 53 relative to body 159 of the pliers, resulting in opening and closing of the pliers.
The pliers on the right side of FIG. 19 are indicated by 161,
Since it is exactly the same as the priorer 158, the explanation will be omitted. In particular, a cylinder arrangement for controlling the pliers 161 is indicated at 162. The entire lifting and lowering of the two pliers 158 and 161, which are integrated with each other by plates 163 and 164, is carried out by a cylinder device 165, whose stem 16
6 is fixed at one end to the block 143, and its cylinder portion is fixed to the plate 164. plate 16
4 raises the hollow tube member 146 which slides in the bearing 168. And member 146
is one body with this and Praya's body, for example 159
Lift up the plate 163 that has become one body. The pliers 158 and 161 of the head 138 described above are hereinafter described as "front" pliers for convenience, but this should not be construed as a limitation on the invention.

The pliers or rear pliers of the head 140 are constructed of the same members as the pliers of the head 138, but a support plate coupled to the rear is added thereto, as shown in FIG. Figure 20 shows two "rear" pliers 170.
and 171, or pliers for the head 140, with a lower plate 174 and one tube member each 172 and 173 (upper portion shown), two plier bodies shown at 176 and 177, and two plier bodies shown at 179 and 180. Praya's jaws (only the right jaw is visible) are shown. Fixed to the plate 174 are supports 182 and 183, respectively, provided with plates 182' and 183', which are arranged over the cavities formed by the jaws of the pliers for receiving the holding punches 2. Ru.

The positions of the plates 182 and 183 are such that when the holding punch is received and held by the jaws, the head 2' of the holding punch hits the plates 182' and 183', respectively, so that the holding punch can be held without the aid of other pliers. Allow it to remain essentially horizontal. Next, I will briefly explain the operation of this system.

At the exit from the dyeing cabinet or the wet skein cradle, one or more skeins held in two holding villages are held by the gripping action of both holding pestles and by bringing them closer to each other, and are moved intermittently as described above. Chen feeder 11-1
Placed on a pair of parallel plates. Since the movement of the chain feeder 11 is linked to the movement of the throttle unit or the brake of the device 12, one of the feeders 11
When the pair of plates has reached a predetermined position loaded with holding villages and skeins, operation of the wringer pliers can be started by suitable control means. When the pair of inlet pliers of the wringer reach the position shown by the broken line on the left side of FIG.
The carriage 65 opens by the action of a respective cylinder device, such as unit 72 in the figure, and then the carriage 65
4 is lowered by the action of cylinder 1 72, which grips a pair of underlying overlapping retaining villages close to their ends, as seen in the example of FIG. It can be raised by The entire frame 60 (FIG. 10) is then moved along the guides 61, 61 (FIG. 9) to the position shown in solid line in FIG. Move horizontally. The cylinder 64 lowers the plier retaining head further, and the pliers then open and place the ends of the retaining village 2 into their respective cups 96.
Any known type or automatic mechanism automatically drives the cylinder device 93 to lower the slide 90 to a position where the skein or skeins are level with the rollers 85 and 86. Next, the cylinder 88 moves the roller 86 closer to the roller 85, as shown by the broken line in FIG. As mentioned above, the latter. The roller 85 is driven by a freewheel device. The cylinder device 93 raises the slide 90 together with the suspended skein at a predetermined speed in order to extract the suspended skein from the squeezing rollers 86 and 85. By intervening a freewheel in the control or drive of the loaf 85, it is possible to avoid the occurrence of so-called blow between the rollers 86 and 85, which occurs in the conventional device due to the difference in the peripheral speed of the two rollers, when the skein comes off in the middle. ing. When the drawing work is completed,
Rollers 86 are spaced appropriately. The wringer frame 60 is then automatically returned to the state shown in broken lines in FIG.
This brings the pair of exit pliers shown on the right side of FIG. 3 into the vertical line of the cup supporting the retaining village. The pliers lower in the open state, close on the holding village 2, rise again and move to the right until they reach a position perpendicular to the loading position of the chain unloading device 13 mentioned above, as shown in FIG. In this way, the loading of a new skein to be squeezed from now on to the slide 90 and the removal of the squeezed skein are simultaneously carried out by the two pairs of wringer pliers. As long as the skein retaining punch is gripped by the exit pliers of the wringer, this retaining village remains overlapped.

When the outlet pliers of the wringer open, the lower or bottom retaining village of the two retaining villages holding a skein or group of skeins is received in the cavity of the first pair of plates 101 coming down, while the remaining The retention village is perched on top of the plate. As the chain moves to the right as seen in FIG. 3 due to the intermittent movement of the chain unloading device 13, the cam or guide device 12 moves downward until the next pair of hollow members 101 come down. It holds the holding village 2 on the upper or top side. As a result, the second skein holding punch also falls into the cavity of the next transitioning plate, and the skein is suspended in a spaced-apart position between two horizontally spaced holding villages, and the unloading device It is transported in a stretched or stretched state. Of course, the movements of the chain feeder, wringer, and unloading device are moved and controlled to enable the operations described above. The movement of the transfer device 14 is also linked to the movement described above.

The spacing between the "front" and "rear" pliers of the transfer device corresponds to the spacing of the plates with cavities of the chain unloading device and is predetermined during installation of the equipment. In this way, the pliers of the transfer device simultaneously grip two separate retaining villages at both ends, and the retaining punches are lifted and conveyed in parallel. The amount of this transport may be varied arbitrarily according to the requirements of each particular system or installation. The transition device generally includes two rods of an expandable rod transition device, as shown in FIG. 17, as disclosed in several pending applications by the same assignee.
Feed the skein on top. This rod 20 is advanced under a separate retaining pestle 2 held in the pliers,
and spaced apart from each other to support the skein. The front pliers (on the left in FIG. 17) then engage and rise so that the rod 200 can pick up or extract the skein from the holding village 2. At this stage, the holding village 2 is floating in space, supported only by the rear pliers, shown as rear pliers 170 and 171 in FIG. When the skein is withdrawn, the last-mentioned pliers also open and the retaining village falls onto a suitable collection device, such as a carriage or belt, as shown at 2101 in FIG. Appropriate changes to the above-described embodiments may be made within the scope of the technical idea of the present invention.
